Obvodny Canal

The channel was dug in 1769–1780s by an engineer L. K. Carbonnier, its course went from the Yekaterinhofka River to the Ligovsky Canal. Initially the Obvodny Canal had a bulwark on the city side.

On December 23, 1804, the construction of the eastern part was started by Ivan Gerard. The city annually allotted 1 mln 230 thousand roubles for the project. The works continued in 1816–1833, managed by Paul Clapeyron and Pierre-Dominique Bazaine. By 1834 the Obvodny Canal turned into the south city borderline, more than 10 km long and 20 m wide.

In the 1840s the L-shaped channel was constructed to allow vessel unloading and moorage. The new French Basin started from the Obvodny Canal near the Alexander Nevsky Lavra and turned West from Glinyanaya street. To allow moorage the Obvodny Canal significantly widened here. The resulted basin is sometimes marked as the "Obvodny Canal basin". The peninsula between the channel and the French Basin used to have railroads from the end of the 19th up to mid 20th century.

From the second part of the century the areas around the Obvodny Canal became an industrial district, as a result the channel became an open wastewater sewer. Still it continued to serve as a cheap and convenient throughway for cargo transportation. In the mid 19th century two railroad stations (Varshavsky and Baltiysky) were opened nearby.

Nowadays the channel is very shallow; navigation is allowed only for small crafts. It is no longer an important waterway, but its embankments turned into major city routes. The channel is crossed by 15 automobile, 6 pedestrian and 1 railroad bridges. Several redevelopment projects are initiated to bring new life into the former industrial buildings.
